SPECIFICATION SHEET

CONTRACT BID SPECIFICATIONS

Ratings

Each unit must meet the following speciﬁ cations:

ARI rating of _________BTU/h cool ing (and _________

BTU/h reverse cycle heating with a COP of _________

at 47° F O.D.)

Electric resistance heat of _________ BTU/h. Total

Amp draw must be of _________ and _________ Watts

at _________ volts.

The unit must remove a minimum of _________ pints of

mois ture per hour when operated at rating con di tions.

The EER must be a minimum of _________ EER.

Unit Chassis

Each unit must be of slide-out design shipped with room

cabinet front-installed. Unit chassis must have the ability

to be installed with 0 clearance from ﬁ nished ﬂ oor. An

electrical power cord must be included with chassis and

installed by the manufacturer to assure proper NEMA 6 or

7 conﬁ guration and UL-approved length. Units less than

250 volts must also have a LCDI power cord. Unit must

be tested for conformance to ASTME water inﬁ ltration

speciﬁ cation ASTME 331-86, which ensures no water

inﬁ ltration when tested at 8" rain per hour at 63 mph

wind for 15 minutes.

Room Cabinet

The monochromatic front of the room cabinet must be able

to be ﬁ eld-secured to chassis to inhibit tampering. Filter

must be accessible without removing room front. Cabinet

depth must not exceed 7⅜” to minimize unit’s impact on

room space.

Coils

Unit coils must have riﬂ ed copper tubing expanded into

rippled-edge louvered aluminum ﬁ ns. Exterior coil must be

of a two-row bent coil design with removable shroud top

to allow easy-access for cleaning of the exterior coil.

Heat Pumps

Each unit must include a change-over thermistor that

sens es an outside ambient switch-over temperature as

low as 24°F, lock-open refrigerant reversing valve dur ing

heat pump op er a tion, temperature-activated de frost

drain, and au to mat ic emergency heat operation to

over ride the heat pump’s change-over thermostat and

bring on elec tric re sis tance heat ers in the event of a

sealed system failure. Unit must not operate com pres sor

and electric heaters si mul ta neous ly.

Com pres sor

The compressor must be hermetically sealed, internally

isolated, rotary-type, and permanently mounted on

rubber isolators. No removal or adjustment of compressor

hold-down bolts is to be required during installation.

Warranty

The warranty is for Full One Year on the entire unit;

Full Second through Fifth Year on the entire sealed

re frig er ant system com po nents; Limited Second through

Fifth Year on functional parts only.

Unit Digital Controls

Unit control must be completely wired and accessible

from the top of the chassis. Controls shall be an LED

touch-pad design with six large, easy-to-read and use

buttons: Heat – Cool – Off – Fan – Temp+ (plus) – Temp-

(minus) and two red seven-segment LED temperature

displays. Unit shall have a green status LED to advise

owner of dirty ﬁ lter, dirty coil, or operational diagnostic

messages. Unit shall have one-button activation via

membrane touch-pad. Unit control board shall have

an 18-pin low-voltage connector to allow for easy

connection to remote wired devices. Unit shall have two

serial-port connectors for easy connection to wired or

future wireless EMS (Energy Management Systems).

Unit must have the ability to easily conﬁ gure owner-

selectable and programmable functions:

• Fan-cycle operation

• Electronic temperature limiting for cooling

• Electronic temperature limiting for heating

• Enhanced dehumidiﬁ cation cooling operation

• Temperature set-back when inactive

• Un-rented temperature set-back

• Load-shedding operation

• Front-desk on-off or temperature set-back

Unit must have the ability to connect to approved

remote devices:

• Wireless or wired thermostat

• Wireless or wired door switch

• Wireless or wired room occupancy sensor

• Wireless or wired room-to-room transfer fan

• Front Desk Control

• RF wireless communications devices

Unit must be able to acquire and display operational

temperature data from up to six installed thermistors

to include:

• IAT—Indoor air temperature (black)

• ICT—Indoor coil temperature (red )

• IDT—Indoor discharge temperature (yellow)

• OCT—Outdoor coil temperature (blue) (heat pumps)

• Green—Miscellaneous temperature (ex. Outdoor

ambient) (optional)

• Orange—Miscellaneous thermistor or analog device

(optional)

Evaporator/Condenser Fans

Direct drive with a permanent, split-capacitor, two-

speed motor. Condensate must be directed onto the

back and sides of the bent coil to aid in evaporation

and removal.

Air Discharge

Must be a sloped surface so that obstructions cannot

be placed on the unit. Discharge conditioned air can be

directed into the room at an angle of 15 or 40 degrees

from the vertical position. The discharge grille must be

of polycarbonate material to resist bend ing, cracking,

rust ing and corrosion.
